We've got a whole house fan and it's awesome. We live in a climate that cools off nicely at night and it works like a charm. We do run the AC for a few hours on really hot days to 'cut the top off' of the heat, but at night the whole house fan comes on. We can then go a large part of a really hot day by managing shades and windows and the house stays nicely cool.
